Multi-parameter mechanical and thermal sensing based on multi-mode planar photonic crystals
Abstract
This paper proposes a novel multifunctional sensing platform based on multimode planar photonic crystals (PPCs). We analytically and numerically demonstrate that the reflection spectrum of PPCs exhibits multiple high-Q resonant modes, and the fundamental and higher-order modes respond distinctively to external mechanical and thermal perturbations, rendering the PPCs superior capability for detection and discrimination of multiple parameters. We further demonstrate simultaneous pressure and temperature sensing with a PPC sensor. Other advantages of PPC sensors include on-chip integration and wafer-scale fabrications.
